* clusters/halo: calc_acc_factor() accepts the fiducial spectrumAaron LI2019-01-281-3/+7
|
* clusters/halo: Fix minor errors along the refactoringAaron LI2019-01-271-5/+4
|
* clusters/halo: Tweak radius_turb() calculationAaron LI2019-01-271-4/+3
|
* clusters/halo: Rewrite is_genuine() to be calc_acc_factor()Aaron LI2019-01-271-16/+10
| | | | | | | Calculate the bolometric emissivity instead of the emissivity at a certain frequency. This should capture the acceleration effect more effectively. In addition, remove the now obsolete config options "fiducial_freq" and "fiducial_factor".
* clusters/halo: Delete the RadioHalo wrapper classAaron LI2019-01-271-92/+0
|
* clusters/halo: Implement calc_electron_spectrum() for multiple mergersAaron LI2019-01-271-0/+118
| | | | | | | For a cluster with multiple mergers, each merger has a different turbulence radius, so the accelerated spectrum needs appropriate adjustment to take the (may be significant) variation of turbulence radius into account.

|
* clusters/halo: Rewrite _merger_time() to get the effective mergerAaron LI2019-01-261-8/+24
| | | | | If the acceleration durations of multiple mergers overlap, the one with the largest efficiency (i.e., smallest tau_acc) is chosen.

|

|
* clusters/halo: Clean up tau_acceleration() methodAaron LI2019-01-251-14/+13
|
* clusters: Assume equipartition between B field and CRAaron LI2019-01-251-1/+1
| | | | | | Equipartition between the magnetic fields and cosmic rays is assumed, i.e., eta_b == x_cr. Therefore remove "extragalactic/clusters/eta_b" configuration option.

* Minor tweaksAaron LI2019-01-181-2/+3
|
* clusters/halo: Update the estimation of radius_turbulence()Aaron LI2019-01-171-4/+8
| | | | | The radius_turbulence is estimated as the stripping radius (r_s) if r_s is larger than the core radius (r_c) of the main cluster, otherwise, r_c.
* clusters/halo: Refactor calc_radius_turb()Aaron LI2019-01-111-14/+37
| | | | | Keep all the calculated properties that can be used to tweak the parameters or to help debug.
* clusters/halo: Implement calc_radius_turb()Aaron LI2019-01-111-0/+36
| | | | | Determine the effective radius of the turbulence region along the whole merging process (i.e., multiple merger events).
* clusters/halo: Add new "RadioHalo" to wrap over RadioHaloAMAaron LI2019-01-101-0/+33
|
* clusters/halo: Renamed "RadioHalo" to "RadioHalo1M"Aaron LI2019-01-101-3/+4
|
* clusters/halo: Rewrite is_geniune() methodAaron LI2019-01-101-0/+30
|
* Bump copyright yearAaron LI2019-01-101-1/+1
|
* clusters/halo: Change radius attribute to calc_radius()Aaron LI2019-01-101-20/+1
| | | | Meanwhile remove the angular_radius and volume attributes.
* clusters/halo: Remove is_geniune()Aaron LI2019-01-101-32/+0
| | | | The similar functionality will be implemented in another wrapper class.

| | | | Move the calculation of Rvir, kT, and B from halo.py to main.py.
* clusters/halo: Set fixed radius for RadioHaloAMAaron LI2018-12-231-2/+14
| | | | | | | Since the halo radius is related to the turbulence injection region size which is further related to the stripping radius, it varies along the cluster growth as mergers happen. Therefore, the finally radio halo radius is determined otherwise and just specified here.

* clusters/halo: Update is_genuine() to return flux factor alsoAaron LI2018-12-221-1/+5

* clusters/halo: Fix kT() calculationAaron LI2018-11-081-3/+2

|
* clusters/halo: Adopt new method for _velocity_turb()Aaron LI2018-11-081-15/+24
| | | | | | | | | | Adopt a new method to calculate the turbulence velocity dispersion. First, the kinetic energy released by the merger is estimated as the work done by the in-falling sub-cluster crossing the main cluster. Second, a fraction of the kinetic energy is assumed to be transferred into the turbulence. The turbulence mass is calculated as the gas mass enclosed within the turbulence region. Finally, the turbulence velocity dispersion is derived.
